the issue of creation IS a religious topic.
Yes. And for that reason alone it has no business in public schools.
And for kids to be informed of the difference between the ToE and creation, then the only place they'll hear the difference is in their religious class because science refuses to present creation as an alternative. IOW in science, there is no choice.
No! In science the "choices" are based on scientific evidence. Various non-scientific beliefs, for which there is no empirical evidence, have no place at all in science.
why dont scientists present a Theory of Creation???
See above.
Is it because they refuse to believe that a God could exist???
It is because there is no empirical evidence for gods and demons, yours or anyone else's.
Religious belief does not constitute scientific evidence, nor does it convey scientific knowledge.
